EAVES-TRCUGH ANGLE oR MITER.

SPECIFICATION forming part of Letters Patent No. 363,044, dated May 1'7,188?.

Application filed March 26, 1887.

T0 aZZ whom, it may concern:

Be it known that I, LA MONT M. BOWERS, a citizen of the United States,residing at Binghamton, in the countyof Broome and State of New York,have invented certain new and useful Improvements in Eaves-Trough Anglesor Miters; and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, and to letters orfigures of reference marked thereon, which form a part of thisspecification.

Similarletters refer to similar parts through out the several views.

My invention is that of an improved joint for the corners and angles ofeaves troughs, and has for its object to strengthen the corners or turnsof the trough to prevent leakage or displacement. The great difficultyin keeping troughs from leaking and getting out of place has been at thecorners and turns,and is caused largely from the weight and accumulationof snow and ice at these points and from the injuries to the structurein removing these obstructions. No miterj oint has heretofore been madewhich possessed the necessary strength and at the same time haspreserved a smooth surface on the inside of the trough.

In the accompanying drawings, Figure 1 shows an angle of a trough withone of my improvedjoints,fromtheoutside,complete. Fig. 2 is a view ofthe samejoint with a piece broken away to show the inside 'of thetrough. Fig. 3 is a vertical section through the middle of the trough,and Fig. t shows the pieces of Fig. 3 separated.

The improvement, as will be seen from the drawings, consists in formingacross the end of one piece and integral with it a rib, a, to stiffenand strengthen the joint. The end of Serial No. 232,586. (No model.)

the trough A is first cut to the proper angle, and then, by means of asuitable press, the rib ais struck up on the metal, having its greatestdepth and weight at the center of the trough. This is shown most clearlyat Fig. 4:, where the comparative depth is shown. The edge of the rib isbrought back just to the level of the bottom of the main trough. The endof the other piece, B, is cut to correspond with the bevel of the mainbed of the part A, the same as though no rib were used, as shown inFigs. 3 and 4. The end is then lapped on the trough A, covering over therib, and soldered there in the usual way. The free edge of the rib a isthen soldered to the under side of the part B, thus making a doublesolder and added strength of the flanged rib across the lap.

The joint may be strengthened by making a rib separate and soldering itto the bottom of both troughs; but in practice I have not found it tomake as good ajoint as when the rib is struck up from one of the piecesand integral withit. This same rib may be used on straight joints, ifdesired, and I do not intend to limit myself to any shape of trough; butitis applicable to all forms of gutter.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

In ajoint for eaves troughs or gutters, a rib integral with and formedupon the end of one of the parts, over which the other part laps and issoldered, with the free edge of the rib soldered to the under side ofthe overlapping part, all constructed and arranged substantially asshown and described.

In testimony whereof I aflix my signature in presence of two witnesses.
